I just did one of those disputes. Some credit/collections company says I had a medical procedure done, and I didn't.

I called up the collections co and asked them to send me some form of a bill or proof that I owe anything, never heard from them. Went on the other day to check out my credit stuff and it's still on there. So I put in one of those disputes. Now all of a sudden they are sending me a bill saying I own $48.

No, I'm not going to "just pay it" because it's a bogus charge. I don't have money to just go handing it out to anyone that just says I owe it to them.
